Passing a null value to the 's' format is explicitly documented as
giving undefined results on Solaris, even on Solaris 11(2).
Do you mean
*printf("...%.*s...", ..., 0, NULL, ...)
i.e. you saw a NULL passed only when we use %.*s with width=0?
Maybe? Not sure what you're asking exactly.
I'm seing what is in the backtrace from gdb and that is prefix is NULL
(0x0) which ends up being printed using some variant of '%s' after going
through the various wrappers.
I hacked around it in run_builtin() as a proof and have also made some
experiments with working around it in setup_git_directory_gently() which
got me a bit further but it looks like there are places that do
if(prefix) which now does not behave as expected because prefix is not NULL.
